The average white brightness uniformity is 4.5% with a maximum of 11.4%. This is a good result. For black brightness, the average and maximum are 5.0% and 15.9%, respectively. That’s quite acceptable, too. In both cases the screen is getting darker from the center towards the edges.

The gamma curves lie close to each other and differ but slightly from the theoretical curve. They betray a slightly higher value of gamma than necessary, which results in a high-contrast image, but you can hardly notice this with an unaided eye.

The curves retain their shape at the reduced settings.

The color temperature modes are set up very well. The temperature varies by less than 500K between the levels of gray, which is a very good result for monitors of this class.

The color gamut is perfectly standard. You have already seen such color gamuts in this review.

The response time average is 15.8 milliseconds with a maximum of 32.5 milliseconds. This monitor is slow even compared with same-class models and far, far slower than monitors with response time compensation technology.

The brightness and contrast ratio are going to satisfy most users.

Take note that the contrast ratio is lower at the max settings than at the default settings because the level of black grows up at a higher rate than the level of white. The contrast ratio is the ratio of white to black, as you know. Added to that, light halftones are indistinguishable from each other at the maximum settings.

Now let’s check out the monitor’s factory-set image modes.

The first two modes might be somewhat brighter. This would also improve their contrast ratio. On the other hand, it’s better to have a lower contrast ratio than an exceedingly high brightness. The sRGB mode is surprisingly bright. The sRGB standard declares a brightness of only 80 nits.

Color reproduction is no good in the Movie mode. The right part of the blue curve goes much higher than necessary. Light blues are indistinguishable from each other.

The curves of all the three colors are higher than the theoretical curve in the Photo mode. And this is the color reproduction you get in a mode that is meant for working with photographs!

The gamma curves are good in the sRGB mode.

There is another problem with this monitor I have to note. Sharpness is too high in each mode and dark objects have the characteristic white contours. It is hard to read text as the consequence. Therefore I would not recommend you to use the factory-set modes of this monitor at all.

Summing it up, the BenQ G900 is a good inexpensive monitor with decent color reproduction setup. Unfortunately, these are in fact all of its highs. If you have serious demands concerning the exterior design or ergonomics of your monitor, about its response time or factory-set modes, you should consider other models.
